Sherri Shepherd Hilariously Scoffs at Peloton's New Christmas Ad

Sherri Shepherd has some advice for hubbies looking to whip their wives in shape for the holidays with the help of a new Peloton -- go for diamond earrings instead, pal.

We talked to the comedian Tuesday night about Peloton's new severely mocked ad -- in which a wife documents the highs and lows of her fitness journey a year after her husband gifted her the workout bike for Xmas. It's hilariously awkward.

Sherri's take on the spot -- that might be why she's single. She mockingly said who wouldn't love a bike instead of diamonds and jewelry. Sherri added, she wishes a future husband would buy her a Peloton ... but you have to see HOW she says it.

If you haven't heard the criticism so far, the general idea is that this fake TV husband is pretty freakin' tone-deaf with his gift. As for the wife ... well, people think she's not all there either with how gung-ho she seems to be about the suggestive surprise.

The criticism has hurt the company's bottom-line too -- its stock price dropped about 6 percent on Tuesday.

Sherri's got a hilarious explanation about why husbands should accept their significant others for who they are. Fellas, before you order that bike ... at least listen to her take. Could save ya in the long run.
